Abstract
The wearable device includes a sound producing device and a sound sensing device. The sound producing device produces a front radiating wave and a back radiating wave while producing the sound. The sound sensing device is disposed on a nodal position where the front radiating wave and the back radiating wave cancel each other on the nodal position.
Claims30
A wearable device, comprising:
- a sound producing device and a sound sensing device;
- wherein the sound producing device produces a front radiating wave and a back radiating wave while producing a sound;
- wherein the sound sensing device is disposed on a nodal position where the front radiating wave and the back radiating wave cancel each other on the nodal position.
A wearable device, comprising:
- a sound producing device, a sound sensing device and a signal processing circuit;
- wherein the signal processing circuit receives a sensed signal produced by the sound sensing device;
- wherein the signal processing circuit performs an operation on the sensed signal and produces a cleaned ambient signal;
- wherein the operation is configured to mitigate a sound signal component corresponding to a sound produced by the sound producing device.
